SLI Set-up help


I have just installed two GTX 670's. I have them up and working in SLI and have run BF3 and Borderlands. However, I am having a couple of issues.

1. two of the three monitors (monitors 2 and 3) keep turning off and I can't find a setting to stop this. I keep on having to hit the menu button on these monitors.

2. When I open an application, the open an inch over from the right-side of the screen overlapping into the other screen.

For reference, they are MSI GTX 670's and my monitors are ASUS ProArt's - all three are the same. Windows 7 pro 64 bit.

If you can give me some suggestions or point me in the right direction, it would be greatly appreciated.

  1. how do you have the monitors wired to the GPU's?
  2. Right...

    Going from right to left:

    1. DVI (GTX card #1)
    2. HDMI (GTX card #1)
    3. HDMI (GTX Card #2)

  3. and how does MSI dictate to have them wired?
  4. They do not, that I know of.

    I have now found a guide on the - so I have switched to all three monitors on DVI...

    Updated drivers.... Issues still exist.

    Oddly, the right monitor (#3) - which is now DVI plug two, on card #1 - blacks out the most... It can be brought back by 1) touching a face button on the monitors and 2) sometimes by hitting my desk. I know this indicates a loose connection, but I have double checked that they are all tight..

    correct me if I'm wrong - the card you have has 1 HDMI, 1 DP, 1 DVI-D and a DVI-I connection

    are you using the DVI-D connector with a Dual-Link cable?


    Here's how I would connect them...
    Mon1-DVI-D Port1 Card1
    Mon2-HDMI Card1
    Mon3-HDMI or DVI-D Port1 Card2

  7. Both DVI connections are dual link - one I one D.... Don't know what that really means - it seems the cables I was using, which are DVI-D can work with either the DVI-D or DVI-I plugs... Anyways, I did find out what the issues was, which was not related to the video cars, cable or connectors.

    As it turns out, the ASUS monitors that I purchased had a "human sensor" i.e. they turn off when they do not sense a human/motion in front of them. With three monitors the right two, and especially the right one was always turning off. This also explains why when I hit the desk they would click back on. Anyways, now that I have turned off that ridiculous function - all is well.

    In the end, I have gone with what you suggested as it will also allow me to get my older 4th auxillary monitor working was well.

    Thanks for the suggestions.
